Password Generator
A password generator creates strong unique passwords that protect your online accounts from unauthorized access. It uses cryptographically secure randomness from your browser to generate passwords that are virtually impossible to guess or crack. Customize length from 4 to 128 characters and choose character types: uppercase, lowercase, numbers, and symbols. The tool also provides a password strength meter and estimated crack time. Security experts recommend unique complex passwords for every account, and this tool makes creating them effortless and secure. The generator uses the Web Crypto API getRandomValues method for cryptographically strong random numbers. Each character is independently selected from the chosen character sets. The tool checks against common password patterns and dictionary words. Entropy calculation shows exactly how many bits of randomness each password contains, with higher entropy meaning stronger protection against brute force attacks.
